About Management and Monitoring Utilities

Greenplum command-line utilities are located in the
$GPHOME/bin directory and are executed on the master
host. Greenplum provides utilities for the following administration tasks:

Installing Greenplum Database on an array

Initializing a Greenplum Database System

Starting and stopping Greenplum Database

Adding or removing a host

Expanding the array and redistributing tables among new segments

Managing recovery for failed segment instances

Managing failover and recovery for a failed master instance

Backing up and restoring a database (in parallel)

Loading data in parallel

Transferring data between Greenplum databases

System state reporting

Greenplum Database includes a dedicated monitoring and management database, named gpperfmon,
that administrators can install and enable. When this database is enabled, data collection
agents on each segment host collect query status and system metrics. At regular intervals
(typically every 15 seconds), an agent on the Greenplum master requests the data from the
segment agents and updates the gpperfmon database. Users can query the gpperfmon database to
see the stored query and system metrics. For more information see the "gpperfmon Database
Reference" in the Greenplum Database Reference Guide.

Greenplum Command Center is an optional web-based performance monitoring and management tool
for Greenplum Database, based on the gpperfmon database. Administrators can install Command
Center separately from Greenplum Database.
